#SpaceDomainNormsOfBehavior 🚀 A rare "no-notice" space launch. Iran's 14 Sep 2024 launch of the Chamran 1 satellite on the solid-fueled Qaem 100 rocket was a rare instance of a "no notice" space launch. There was not a Notice to Airmen and Mariners (NOTAM) issued. Iran and North Korea are the only two space-launch capable countries who are not signatories to the The Hague Code of Conduct against Ballistic Missile Proliferation (HCoC) (ref https://www.hcoc.at/). Resolves to a hcoc.at URL. Such notifications prior to launch mitigate potential false alarms of a missile weapons launch. ❓ Historians and policy folks: would like to learn and understand more. The HCOC has only existed since 2002. What preceded the HCOC and governed US and Soviet launch notifications during the Cold War???

U.S. Army Maj. Gen. Richard Zellmann, Deputy Combined Joint Force Space Component commander, delivered the closing remarks during the National Prisoners of War/Missing in Action (POW/MIA) Recognition Day ceremony at Vandenberg Space Force Base, Calif., Sep. 20, 2024. Zellmann, along with members of Team Vandenberg, gathered to honor and remember the sacrifices made by brave service members who were captured in conflict or remained unaccounted for. Their stories exemplified the indomitable human spirit and the power of hope, which sustained them through unimaginable hardships. As they waived the POW/MIA flag high, they recommitted to bringing home those who remained missing and ensured their sacrifices were never forgotten. #POWMIARecognitionDay #NeverForget #HonorOurHeroes  #POWMIA  #BringThemHome 📷: Space Launch Delta 30

Another giant rock glides past Earth. A giant 720-foot asteroid named 2024 ON is expected to make its closest approach to Earth today. The asteroid will safely pass Earth at a distance of 997,793 kilometers, which is 2.5 times the distance between the Earth and the moon—considered safe for Earthlings but a negligible distance by cosmic standards.  Deep Space Dynamics #wedeliver

This is a nice article from NASA. The one centrality that was left out is the word 'known'. The number of 'known' asteroids has increased by an order of magnitude since 1999. It turns out we live in a crowded neighborhood where collisions take place frequently. It's time we had a proactive strategy in place to deal with potential collisions.

Assembled into this animation, observations from NASA’s Goldstone Solar System Radar show the tumbling asteroid 2024 MK shortly after it made its closest approach to our planet, 184,000 miles (295,000 kilometers), or slightly more than three-quarters of the distance between the Moon and Earth, on June 29. Earth’s gravity slightly altered the 150-meter-wide asteroid’s orbit as it passed.  Credit: NASA/JPL-Caltech Deep Space Dynamics #wedeliver

Had #Juice been coming from Sunward, we would never have seen it. "On 6 July, a previously undetected object triggered the automated ESA and NASA warning systems that alert the global hashtag #PlanetaryDefence community of a new potentially hazardous asteroid approaching our planet. It turned out that this object, estimated at around 50 m in diameter, was much smaller, harmless, and even had a name: Juice."

By the time an asteroid gets this close to Earth, it is too late to safely move to a new orbit. We have to make slight adjustments (1/100th of a degree) between the orbits of Mercury and Venus, sending such rocks to safe pre-approved locations. Deep Space Dynamics #wedeliver

This is a great animation of stable Near Earth Asteroids. What it doesn't show are asteroids with eccentric elliptical orbits. Such asteroids move with more comet-like orbits and will approach Earth from sunward. Imagine I shine a flashlight in your face while tossing one grain of sand at a time at your nose. You may see that grain of sand a tic before it hits you on the noggin. You may not. That is where we stand with asteroids with eccentric orbits. These eccentric rocks or gravel piles move at nearly 12 km/sec. For improved detection and diversion, we must have an early warning detection system closer to the sun; a dew line for a different potential apocalyptic strike. We have the solution at Deep Space Dynamics. #wedeliver United States Space Force Space Force Cadet Corps US Air Force School of Advanced Air and Space Studies (SAASS) United States Air Force Small Business Office, Air Force Sustainment Center Department of the Air Force (USAF & USSF) Chief Modeling & Simulation Office US Army Naval Special Warfare Center Marine Corps Systems Command U.S. Coast Guard SDA TAP Lab National Reconnaissance Office (NRO) SpaceX

Dawn, the first spacecraft to orbit two extraterrestrial destinations - Vesta and Ceres - showcases an incredible proof of concept beyond Mars. At Deep Space Dynamics, our goal is to make multiple stops on every mission to send back valuable data, paving the way for a more promising future for all mankind. #wedeliver
